| Abstract | We investigated the hydrostatic and shear strain components introduced in the graphite hexagons by applying hydrostatic pressure to single-walled carbon nanotubes. The vibrational modes are expected to show different pressure derivatives depending on the polarization of the eigenvector with respect to the nanotube axis, but independent of chirality. A comparison with tight-binding calculations allows us to estimate the Gruneisen parameter ~1.24! and the shear phonon deformation potentials ~0.41!; they compare favorably with experimental results on nanotubes. |
